I ELECTRIC-SWITCH MECHANISM.

Application filed November 29, 1921.

To all whom it may concern:

Be it known that I, ELIAS ZARAGOZA, acitizen of the United States, residing at Manila, in the Philippine Islands, have in vented certain new and useful Improvements in Electric-Switch Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a simple inexpensive and eflicient switch mechanism which by various arrangements of the parts is adapted to perform the functions of a circuit breaker, a circuit closer,

- a vibrator, a current limiter, a relay or a re.- peater, and wherein the use of pivoted members and others involving the factor of friction are eliminated and the construction and arrangement of the parts is such as to afford the maximum sensitiveness, delicacy and refinement in operation while the pos-' sibility of, disarrangement or displacement of the parts under service conditions is minimized; and with these objects in View the invention consists in a. construction, combination, and relation of parts of which a preferred embodiment is shown in the drawings, wherein Figure 1 is a side view, and

Figure 2 is an end View of a switch embodying the invention,

Figure 3 is a plan view of the same,

Figures 1- and 5 are end and plan view-s showing a rearrangement of the parts to adapt the structure for use as a circuit closer,

Figures 6, 7 and 8 are detail views of the carrier for the vibrator or tongue,

Figure 1 is a side view and Figure 2* is an end View of a modified construction of the switch,

Figure 3 is a plan view of the same,

Figure l is a sideview showing an arrangement of the parts to adapt it for use as a circuit closer.

In the form of the invention which is illustrated in Figures 1 to 3 inclusive, the magnet 10 is of U-shape or form having a U-shaped core 11 engaged by the spool or winding 12 and the opposite poles 13 and 14- of which, when the device is arranged in the vertical position indicated in the drawings, the arm or pole let constitutes a base for attachment to a suitable support and Serial No. 518,724.

as asupport for the vibrator or tongue 15.

This vibrator or tongue, of elastic or resilientmaterial and preferably of a sensitive quality, either constitutes the armature or may carry a soft metal armature 16 as shown in the drawings, said tongue or vibrator being attached at one end to the flange 17 at one end of a carrier 18 which is adjustably mounted upon the foot 14 to provide for varying the position of the tongue or vibrator. In the construction illustrated this carrier consists of a plate slotted as shown at 19 for engagement by the binding screw 20 and having a depending flange 21 bearing against the edge of the foot to guide the plate or carrier in its adjustment and insure a proper positioning of the tongue or vibrator.

\Vhether the tongue or vibrator constitutes the armature or carries an armature 16 as illustrated, there are provided contacts 23 and 24-, either of which may be employed at the option of the operator and in accordance with the purpose for which the switch is to be used, and if to be used as a circuit breaker, the contact 24 is arranged in operative relation with a contact 25 which is carried by a support 26 preferably adjust-ably mounted upon a post 27 or its w equivalent and adapted to be moved toward and from the contact 24 according to the strength of current which should be carried or conveyed from the contact 24L to the contact 25 without the breaking of the circuit, it being obvious that if the device is'to be used as shown in Figures 1 and 2 as a circuit breaker, and the contact 2st is ar anged in engagement with the contact 25 and the current passing through the contact and also through the winding of the magnet exceeds the predetermined strength, the armature will be attracted by the magnet and the contacts 24 and 25 will be separated to break the circuit.

In'the construction illustrated in Figure l, the contact 25 is reversed in position with relation to the tongue or vibrator and is disposed in operative relation with the contact 23 so that when the circuit is closed through the winding of the electromagnet the attraction of the armature will serve to close the circuit by bringing the contact 23 into engagement with the contact 25. In this instance also the carrier 26 is adjustable to vary the gap between the contacts 25 and In the modified construction illustrated in Figures 1 to 4 't11e 'eIectiioniagnet is of the 'bar type having the core 1-1 straight and extending axially through the winding or spool 12 and preferably adjustable longitudinally therein and adapted to be secured at the desired adjustment by means of a collar 18 fitted with a set screw The extremity'of t'he'coie" is disposed adjacent to the tongue or vibrator 15 which carries the contacts "23 and 245 of which the latter a's'shown in Figure 1 is ar anged inoperative relation with a contact 25 "carried the "adjustable 's u-p'poftac so that in this instance the device "mustang-s a circuit breaker.

- In Figure et the paits areshewn arranged for use "as a ci1'c"uitclosei', with the contact 28 arranged in operative relation with and adapted to be brought into engagement with a contact at the end er the ma net core.

' From the above description it will be obvious that the device can b eiis'ed 'n'ot' only as a circuit breaker and circuit "closer under the conditions indicated but "also as a relay and repeater and-also and more particulai -ly as a current limiter. As a current limiter the electromagnet and contacts are placed in adjusted and designedyand should the consuming device such as a "lamp or otherwise connected to or included in*the circuit re quire a greater amount of 'cur'rent the vibrator, consi s'tingias indicated of a spring or diaphragm, will be caused to Vibrate "{to effeet "the alternate opening and closing of the circuit in such a wa that the mean effective current flowing through the circuit will be constant and equal to the maximum current for which the instrument was adjusted, and if the current consuming device therefore -is a lamp or a group oif lamp's they will be caused togrow dim o'r'the lig'ht therein will be caused to fiiclc ei' according to the characteristics ofthe spring'vibmter,

or diaphragm, and the contacts carried thereby. I V

is a relay and repeater the "eirc'uit' into' which thecr1iiei1t is repeated *or relayed is usuallycon'necte'd in series with the contacts, the electromagnet being in series with the original or primary circuit, but obviously both primary and repeated circuits may be 'the same under certain conditions as will be readily understood.

Thespecial-advantages of the device hereindescribed reside in the simplicity and compactness of construction thereof, and the 'cheapne'ss of manufacture together with the efficiencyof the device, it being obvious that the instrumentfi'nay be of small size with the number of parts limited to :pro- 'v'ide against any tendencyto disarrangenient or displacement. It will be noted that'there are no pivots o'r other small moving parts likely to involve trouble. or cause failure 0 device by reason'of displacement or otherwise, and moreover, there being 'no frie "tionally related moving parts, it is obvious that the durability ofthe device is practical- 1y unlimited. i

In the construction illi'istrated in Figures =1-5 it is preferred, as shown to extend the armatuij-je terminal 28 inwardly into overlapping relation with the pole otth'e' magnet, so as *to be positively influenced thereby, regardles of the adjustment of the armature necessary to provide the required gap between the contacts to suit the strength of current which is to be carried without dis- =t urbin 'the normal relation of the contacts.

"Whatisdaimed is A mechanism for the purpose indicated having an electro-magnetprovided with :pole pieces, a'carr'ier mounted on one of the :pole pieces, a yieldable vibratorextending from the carrier and being normally 'sp'aced' from the other pole piece,'sa id pole pieces being "extended to dispose the vibrator in offset relation to the magnet, said carrier having an elongated slot a'securing means'to pass through said elongated slot, and a fiange extending trom the 'carrier and engaging the adjacent pole piece to position the carrier.
